ATTACl-IMENT FOR TELEPHONES-' No. 825,184. v Specification ofApplication filed January 22,1906. Serial No 297,233.

mary object the provision of novel means for sounding a continuous alarmwhen the telephone lin s or which may be arranged to sound an alarmsimultaneously with the telephone, the duration of the alarm being thesame as the telephone.

My invention aims to provide an attachment for telephones which may beassociated direct with the telephone or may be placed at a considerabledistance therefrom to sound an alarm simultaneous.with the telephone andnotify persons that a call has been made over the telephone. In thisconnection my invention is particularly adapted for warehouses,factories, and large buildings where the occupants are oftentimes aconsiderable distance away from the telephone, conseipliently not heinable to hear the same when t e telephone-bell rings.

To this end I have devised an attachment comprising a small andinexpensive mechanisnrwhich is located upon a telephone, and inconpinctlon with the mechanism I employ a battery and an' electrlc bellwhich arecon- .nected withthe mechanism whereby when the same isactuated the electric bell will be sounded until the telephone-call isan swered or may be made to sound an alarm of the same duration as thetelephone-call.

The detail construction entering into my invention will be hereinaftermore fully. described, and specifically pointed out in the claims, and,referring to the drawings accompanyin this application, like numerals ofreference esignate correspondinglparts tlnoughout the several views, inwhic anism thereof.

My invention resides in pro- 3 3 with a depending shield or plate 5,upon which is, pivotally mounted a connecting-rod 6, said rod beingretained in engagement with the plate or shield 5 by a screw 7, theconnect and free to move thereon for a short distance in the directionof the length of the screw. Directly above the screw 7 I provide theplate or shield 5 udth a notched retainin strap 8, which is adapted tonormally ho d the connectin -rod in a fixed position cen taming-strap.Upon the insu ation-plate 5, at opposite sides of the dependin end 9 ofthe connecting-rod, I mount angular lugs 10 10, which carryadjusting-screws 11 and 12.

The plate or shie d 5 adjacent to the lower end of the connecting-rod6'is' provided with a U-shaped plate or strap 16, carrying screws 17 and18. The plate or strap 16 is connected bya wire 19 with a conventionalform of electric bell 20, said bell being connected by a wire 21 with abattery 22, which in turn is 7 of theconnecting-rod 6.

The spring 14: moves thedepending end 9 of the rod 6 into engagement with the screw 1 whichcloses the circuit and causes the electric hell 20 to continuously ringuntil the connecting-rod 6 is returned to its normal position or thebattery 22 becomes exl1austed. When the attachment is arranged to soundan alarm of the same duration the telephone, the spri: i4 is releasedand the tension upon the spring 15 increases until. the connectin -rod 6rests lightly the tapper 4., as shown in Fi 1, The screws 17 and 18 arethen adjusted until the ends of said screws almost touch the dependingend 9 of the connectingrod W the telephone rings the depenoin' "i 9 theconnectingrod 6 Will vihr between the ourw of the screws 17 and 18, thusclosing, the circuit and causin the bell 20 to rul as lon as the ta l) bt:-
